Flightradar24 has emerged as a crucial platform for monitoring air traffic, particularly during significant global aviation crises. Recently, the platform has been instrumental in tracking the travel disruptions caused by the escalating US-Israel conflict with Iran, showcasing empty airspace over the Middle East.
The Swedish flight tracking tool originated from a flight price comparison portal. Founders Mikael Robertsson and Olov Lindberg initially created the air traffic page to attract more visitors to their website. As interest grew, this feature quickly outshone the original purpose, evolving into what is now Flightradar24.
“Very soon this flight tracker … became more popular than the price comparison [tool] itself,” recalled Robertsson, reflecting on the platform's unexpected success. The turning point came in 2010 during the eruption of Iceland's Eyjafjallajökull volcano, which grounded flights across Europe and drove millions to Flightradar24 to monitor the situation in real-time.
This event marked the beginning of significant user engagement with the platform, as it provided a live feed of air traffic during a crisis. According to Fredrik Lindahl, the current CEO of Flightradar24, various major aviation events have since attracted substantial attention, from the mysterious disappearance of Malaysia Airlines Flight 370 in 2014 to the disruptions caused by the COVID-19 pandemic in 2020.
Flightradar24’s audience spikes can occur not only during large-scale crises but also for individual flights of public interest. Notably, the evacuation of Russian opposition figure Alexei Navalny to Berlin in 2020 and his subsequent return to Russia in 2021 saw users flocking to the platform to follow his journeys live.
In recent days, the turmoil caused by the US-Israel war on Iran has resulted in widespread airspace closures and significant travel chaos. Following airstrikes by the US and Israel and retaliatory missile launches by Iran, many countries in the region swiftly shut their airspace. Flightradar24 vividly illustrated the impact on aviation, revealing two narrow flight corridors filled with aircraft symbols as air traffic rerouted to avoid conflict zones.
“For each big aviation event, we do get a big traffic spike, and then it sort of dies down,” Lindahl explained. However, he noted that the traffic tends to remain slightly elevated even after the initial surge. The journey of the late Queen Elizabeth II's coffin in 2022 exemplified this; it drew an unprecedented 4.8 million viewers as it traveled from Edinburgh to Northolt.
How Does Flightradar24 Work?
Flightradar24 operates through a sophisticated network of approximately 58,000 radio receivers, including a few located in Antarctica. The system began with just two receivers installed by Robertsson and Lindberg at their homes after they discovered the possibility of monitoring air traffic using simple devices.
“It sounded like something impossible,” Robertsson admitted. “Like, how can you track air traffic with a small box? I would probably classify it as a scam if I found something like this today.” Each aircraft transmits flight data—such as callsign, position, direction, speed, and altitude—collected by the network of receivers.
By early 2010, Flightradar24 was attracting around 40,000 daily visitors. The volcanic eruption in April of that year led to a significant surge in interest, with the platform reporting around four million visitors within hours as flights were grounded across Europe.
As conflicts erupted in Iran and the surrounding region, traffic to Flightradar24 more than doubled, highlighting the platform's role as a vital resource during crises. “Saturday was a spike, then we went down a bit on Sunday, and then a bigger spike on Monday,” Robertsson noted, indicating the fluctuations in user engagement.
Flightradar24 has successfully monetized its audience by offering a premium subscription service that provides additional data, which accounts for approximately 70% of its revenue. The platform also sells commercial packages to industry operators and generates income through advertising.
The success of Flightradar24 is largely due to its community of aviation enthusiasts who contribute to the network by hosting receivers. “We’re really trying to have a very strong free product because … what underlies all this is the crowdsourced aspect of Flightradar24,” Lindahl emphasized. This strategy not only maintains a reliable map but also encourages users to become more involved with the platform.
Today, Flightradar24 has over 1.5 million paying subscribers and typically attracts around 60 million free viewers to its website each month. As the platform continues to evolve, it remains an indispensable tool for tracking global aviation events.
